The-present invention relates to iiinprovfiments in string: fasteners and, adjusters for musical instrument; strings, and particudeviceoi' this character! especiallv desirable f r v olinwi e' E-strings. Wire strings as: ordinarily used upon violins. are very diff cult to adjust to the exact tone because the Wooden pegs emploved for adjusting the string would not to properly, tuneawire string; :It isv an ofmv invention-therefore, to provide at ach to the tail pieceof the, violin with facility and by means of which. it may be adjusted to the very finest degree, and slippage will -be-preventec ,A further object is toenable the loop of to the'device and easily removed-,that is, its

to provide come: loose, order, and which will be the string to be readily secured removal will not be made; difiicult by the tight binding of the loop caused by the, Other; objects. are such means which will not beand will not readily get out of stretching of the string.

simple in construction and inexpensive to manufacture WVith these and other objects in view,oin-1 bodiments ot-niv invention are, shown lathe accompanying drawings and these embodiments will be hereinafter more iully described with reference thereto and the invention will befinally pointed outn the.

The tightening of the string in this manner is very easy and positive, permits of he most delicate adjustment of the string. The direct drawing of the end of the nut into engagement with the end of the barrel hythe string will prevent any accidental dis-- placement of the nut, while t ie low pitch of the threads will permit it to be turned with facility by the finger. V

Inasmuch as the hook is of equal cross section or it may with the same purpose-be tapered toward its end, it will enable the quick removal of the string when it is desired torenew it, it being only necessary to slip the same off of the end of the hook, and this will not be prevented by thetightbinding of the loop upon the hook due to the tightening of the string.

In orderto prevent loss of the device from the tail piece, when the string is not drawn tight, Iprovide an annular groove 21 and a head 22 at the end of the post'to which may be secured a spring'snap button or head 23, or if desired, the end of thepost may be threaded and a nut screwed thereon.

In-Fig. 6 I have'illustrated a modified form of construction in which the barrel is provided with a post 25 threaded at its end 7 and inclined forwardly, the same being of a size to fit substantially snugly in the aperture of the tail piece, and provided adjacent the barrel with a shoulder'26 engaging the upper surface of the tail piece, while a nut 27 is screwed upon the threaded end and engages the under surface to secure the device In Fig. 7 I have illustrated another modi fied I form of my invention comprising a plate 30 disposed at the under side of the tail. piece and projecting forwardly therefrom, a post 31 provided thereon extending upwardlythrough the aperture 17, a nut 32 provided upon its upper threaded end 'securely fixing the device to the tail piece. A lever 33 is pivoted at 34 to the forward end of theplate 30, one arm of the lever extendingbeneath the said plate where it is engaged at its end by the end of a thumb screw 85 disposed in a threaded hole 36 extending through the post 31, while its other arm is uprightly disposed in front'of the tail piece and is provided with a hooked end portion 37 with which the looped end of the string is engaged. By adjustment of the thumb screw, the hooked end of the lever is moved in or out and thereby the string is adjusted. The hook securely holds the string while at the same time it permits of its attachment and removal with facility.

I have illustrated and described preferred and satisfactory embodiments of my invenmusical instrument string,

tion but it is obvious that changes may be .made therein within the spirit and scope thereof as defined in the appended claims.

I claim:

1. In combination with a musical instrument having a string attachment member, and a string provided at its end adjacent said string attachment member with a loop,

astring fastening and adjusting device,

comprising means secured to said string attachment member, adjustable means movable in a direction longitudinally of said string and provided at its end adjacent the looped end of said string with a" portion bent upwardly and forwardly from its base in a vertical plane, and bent rearwardly from said upwardly and forwardly bent pori and without increasing the diameter of'said loop.

2. In combination with the tailpiece of a musical instrument provided with an aperture, a string fastening and adjusting device comprising a member having a longi t-udinal passage therethrough, another member non-rotatably' and slidably engaging said passage, and provided with a screw threaded portion extending therefrom at 7 one end, means at the other end of said member adapted to be engaged by the end of a a nut engaging said screw threaded portion, having its periphery extending substantially beyond the surface of said first-mentioned member, and adapted by turning to adjust said other member longitudinally of said first-mentioned member, and a post carried by said first-mentioned member extending therefrom at an angle and engaging said aperture of saidtailpiece, and adapted to support said first-mentioned member at an inclination to said tailpiece with the end adjacent said nut relatively higher than the opposed end to space the periphery of said nut from said tailpiece to permit ment.

. 3. In combination with a musical instru' ment tail piece provided with an'aperture, a string fastening'and adjusting device comprising a member having a longitudinal passage therethrough, another member engaging said passage,'adjustment means for adof its free turning moveend of said other member adapted to beento the axis of said aperture, tightening of gaged by the end of a musical instrument said string adapted to Wedge said post in string, said adjustment means adapted to holding engagement With said aperture. 10
